2 Claims.

The, present invention relates to new and useful improvements in shoesole presses of the pneumatic type and has for oneof its important objectsto provide, in a manner as hereinafter set forth, a, machine of this character embodying a novel construction; combination and arrangement of.parts?through the medium of which a comparatively large number of jacks will be conveniently located within the reach of an operator.

Another very important object of the invention is to provide a shoe sole press of the character described embodying a novel valve controlled air system whereby each of the jacks may be inflated and deflated as desired.

A still further important object of the invention is to provide a shoe sole press of the character described the use of which will result in a material increase in output or production.

Other objects of the invention are to provide a shoe sole press which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a vertical sectional view through an intermediate portion of the machine.

Figure 2 is a View partially in top plan and partially in horizontal section with parts omitted.

Figure '3 is a detail view in vertical section through one of the air control valves.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a table I of suitable material, said table being arcuate and annular in plan, as illustrated to advantage in Fig. 2 of the drawings. Supporting legs 2 are provided for the table I. Mounted at spaced points on the table I are jacks which are designated generally by the reference numeral 3. In the accompanying drawings eight jacks are indicated as located on the curved table I in an annular series, the individual jacks being disposed radially with their heel ends directed inwardly and both ends freely accessible to the operator. Each jack 3 comprises a base 4 which is secured to the table I, by bolts 5 and has an outwardly and upwardly inclined supporting face. Mounted on the base 4 of each jack is an inflatable pad or the like 6. Projecting from the ends of the base 4 are integral, apertured ears 1 in which are rigidly mounted upstanding shouldered bolts 8.

-Mounted on the upper portions of the vertical bolts 8 is ahold down 9 for the shoe !0. Formed integrally withrthe ends of the hold down 9 are 515 apertured ears H which accommodate the vertical bolts Sand are supported by the shoulders thereon. Nuts H! are threaded on the upper and lower end portions of the bolts 8 for anchoring the hold down 9 to the base 4. Mounted beneath the hold down 9 is an adjustable toe or instep pad l3.

Mounted beneath the table I on the front legs 2 of said table is an air conduit or line M from a suitable source of supply. Branches l5 connect the air line M to the several inflatable pads 6, said branches passing vertically through the jack bases l, as at l6. Interposed between the branches l5 running to the individual jacks and the air line M are multiway control valves I1.

Each control valve ll includes a casing I 8 in Which a tapered core [9 is rotatably mounted. Diametrically opposite intake and outlet ports 26 and 2|, respectively, are provided in the casing 18. The casing I8 is further provided with an exhaust port 22 to the atmosphere. The core I9 is provided with a diametrically extending passage 23 with which a circumferential groove 24 communicates at one end. Fixed on one end of the tapered body 19 is an angular operating arm 25.

. Each valve l l is manually operated through the medium of a foot treadle 26 one of which is pivotally mounted beneath each jack at an intermediate point for rocking movement in opposite direotions on a suitable base 21. Each treadle 26 is connected to a valve arm 25 by a rod 28 having clevises 29 on its ends.

Arranged in spaced, concentric relation to the inner periphery of the arcuate table I is a rail 39 on which a solvent cup 3| is adapted to be slidably hung. It will be noted that the rail 3!] extends from end to end of the arcuate table I. Any suitable supporting means may be provided for the rail 30. The arcuate table is shown as comprising about of a circle and it will be understood that this may be assembled with other similar sections to form an annulus or a part of an annulus within which the operator may move conveniently from one jack to another.

Briefly, the operation of the machine is substantially as follows: 7

The lasted shoes being made, with the soles cemented and applied thereto, are mounted one by one in the jacks 3 of the machine. This is done by the operator who stands within the concave curve of the frame where he can conveniently move from jack to jack. As soon as each shoe has been positioned the corresponding valve I1 is turned to the position shown in Fig. 3 of the drawings through the medium of the foot treadle 26 for inflating the pad 6 to the desired pressure. When it is desired to deflate the pads 6 the foot treadles 26 are rocked in the opposite direction for I rotating the valve cores 19 to a position wherein the branches l5 are in communication with the discharge ports 22 thus exhausting the air inthe pads 6 to the atmosphere. The combination and arrangement is such that the jacks 3 are separately and conveniently controlled. The solvent cup 3| may readily be shifted to a position adjacent any of the jacks 3 on the rail 30.

It is believed that the many advantages of a shoe sole press constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the machine is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What isclaimed is:-

1. A shoe sole press of the character described comprising a substantially arcuate supporting structure, a plurality of spaced jacks mounted on the supporting structure in an annular series leaving both ends of each jack freely accessible, each of said jacks including an inflatable pad, an air line mounted on the supporting structure for connection with a source of air supply, branches connecting each of the inflatable pads with the air line, multiway valves interposed between the air line and the pads for selectively establishing communication between said air line and the pads or between saidpads and the atmosphere, and means for manually actuating each of the valves.

,2. A .sole press of the class described comprising, in combination, an arcuate supporting frame, spaced jacks including inflatable pads mounted on said frame in an annular series and each extending beyond its circumferential edges thereby leaving both ends of the jack freely accessible, an airline located beneath said frame, branches between said airline and the padof each jack, and .a :manually controlled valve :in each of said branches for selectively establishing communication between said air line and the pads, or between said .pads and the atmosphere.
